Just after seven pm last Friday (25 September) a man called Steve was riding southbound across Waterloo Bridge when he hit a bump in the road and fell of his bike.
Blood started flowing out of his right eyebrow and ear as he lay on the floor and a small crowd gathered to see if he was hurt.
I called an ambulance while a man called Phillip and a woman called Anna-Lise moved him and his bike onto the pavement. I took instruction from the emergency services phone assistant and passed on messages to Steve, while Anna-Lise and Phillip checked him out.
We waited with Steve while a paramedic came. He bled on the white barrier at the side of the bridge, the pavement and himself but rested his head on his bag while laying on the ground in good spirits.
The paramedic drove passed us and I had to call 999 again but once again a calm, professional emergency services bod straightened things out and got a message to the paramedic.
A few minutes passed and Anna-Lise, Phillip and myself waved our arms around in a line to ensure we weren't missed on the paramedic's return.
We weren't, so after performing some important checks the man in green thanked us for waiting with Steve and let us go while he and Steve waited for an ambulance.
As Philip and I walked off northbound towards Aldwych the flashing lights of an ambulance sped by going north, did a U-Turn at the traffic light junction by the strand and zoomed passed back passed us south to pick up Steve.
It felt good to get involved and help someone for once, even if all I did was make a couple of phone calls. Steve might have had a long wait in St Thomas's on Friday night and they might have had to keep him in for observation but I'm pretty sure the fella's going to be OK.
During our wait Steve told us he'd fallen off his bike badly before, albeit injuring his hip.
No serious bike rider goes through life without getting a few scrapes of varying severity, but Steve should probably think about some protective headgear when he takes to wheels.
Shortly afterwards I was walking westbound along William IV Street recounting the above story on my phone in loud, excited and extremely animated fashion. A belligerent middle-aged Irishman spouted some "feck, drink, girls," crap at me as I walked passed him, but his wife quickly chastised him.
Pah, you do one good deed in a lifetime of ill behaviour and some joker won't even let you bell your mum to tell her without sticking his unwanted nose in.
